WebIn hydrometry, the volumetric flow rate is known as discharge. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration of a flux over an area gives the volumetric flow rate. WebSep 16, 2024 · Flow Rate. Flow rate is an indicator of the amount of water flowing through a point at a specific time. With the help of a flow meter, you can measure the flow rate.

The control valve, however, tries to maintain a steady pressure. As a result, the flow rate varies as the suction pressure varies. In some cases, the flow rate may drop to below the recommended minimum at very low head conditions. dewi shinta

"In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol Q (sometimes V̇). It contrasts with mass flow rate, which is the other main type of fluid flow rate. In most contexts a mention of rate of fluid flow is likely to refer to the volumetric r… " - Flow rate vs discharge

WebFeb 27, 2024 · In the case of a positive displacement pump, increasing the pipe length causes the fluid pressure at the pump end of the pipe to go up at a constant flow rate, until the pressure limit of the pump is hit. Increasing the pipe length beyond that point will cause the flow rate to fall because the pump is now behaving like a constant-pressure pump.
